BUTTON, STUD, 8w.

SPECIFICATION forming part of Letters Patent No. 224,386, dated February 10, 1880.

Application filed Oetobe r30,1879.

To all whom it may concern Be it known that I, ISAAC N. OAPRON, of Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Buttons, Studs, &c.; andI do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to buttons for sleeves and like purposes, and is also adapted for use in shirt-studs. It belongs to buttons of that class in. which the inner disk is made movable upon the stud or shank,.so that it maybe brought into line with the stud or shank for the purpose of insertion in to the button-hole, and afterward turned at right angles to secure'it in place.

The invention consists of the special construction of parts, all as hereinafter set forth, and particularly pointed out in the claims.

In the drawings hereunto attached and forming part of this specification, Figure 1' is a central section on line a: a: of Fig.2. Fig. 2 is a section on line :1 g of Fig. 3, and Fig. 3 is a side view with theinner disk extended.

In these figures, (it represents the outer disk of an ordinary sleeve-button, which may be of any material or with any ornamentation To this disk is firmly attached a hollow flattened stud, b. Extending across the longer diameter of this hollow stud or shank is a staple, 0, (shown more clearly in Fig. 2,) which is' firmly: secured Within the said stud or shank. There is also a pin, d, placed centrally within the stud or shank, pressed constantly outward by. a small'spiral spring, 6.

The stud is cut away on each side, as shown at i 'i, to admit a transverse bar, k, which is fixed to the inner disk, Z-,in the manner shown in Figs. 2 and 3. This transverse bar passes under the staple, by which connection the inner disk is held inseparable from the stud.

The ends of the transverse bar at the edges turn up and join the outer shell of the inner disk, thus forming aclosed loop, which allows the inner disk to be shifted from side to side upon the stud or shank. This transverse bar V has a central indentation on the surface next the stud, into which the outer end of the central pin lodges, and, being pressed out by its spring, it holds the inner disk in its proper place centrally upon the stud or shank.

The transverse bar may be slightly curved on said inner surface to allow for the passage of the end of the pin from side to side.

The inner disk is cut away, as shown at n n, on each side of the transverse bar where it joins the disk, and the bar is flattened or formed with a small depression, 0, on each side, on line with the'edge of the disk.

By means of the construction last described the disk is held on edge, the projections 10 p on each edge of the stud entering the notches n aon the edge of the disk, while the central pin presses against the depression 0 in the bar. By. this the disk is locked in place with sufficient firmness to hold it for insertion through the button-hole. When the inner disk is turned so as to be parallel with the outer, it may he slipped along easily until the indentation'at the cen-- tral point of the transverse bar arrives at the head of the central pin, when the latter looks 'it centrally in place securely against any accidental displacement, though it may be moved from side to side with the fingers with case.

It is obvious that the notches a n and indentation 0 may be placed upon one side only, if desired, and that the indentation 0 may be omitted.

I am aware that buttons have been heretofore known with an inner bar or disk attached to the stud or shank and made capable of sliding on said stud and of being'turned edgewise for insertion into the button-hole, and then to be turned parallel with the outer disk, so as to serve the purpose of an ordinaryinner disk of a button; but

What I claim, and desire to secure by Letters Patent, is-

1. The combination, with the outer disk of the button, of the hollow shank or stud, of the staple fixed therein, together with the spring and central pin, and of the outer disk having i In testimony whereof I have signed my name IO the transverse bar, as and for the purposes set to this specification in the presence oftwo subforth. scribing witnesses.

2. The combination, with the stud or shank 5 of the button provided with the staple and ISAAC N. GAPRON.

central pin with spring, of the inner disk having a transverse bar with its central indenta- Witnesses: tion, and with notched edge or edges, as and B. PORTER, Jr., for the purpose set forth. T. A. BARDEN.
